Toyota is preparing to introduce a next-generation advanced driver assistance system (ADAS) in 2028, aiming to compete with Tesla’s Full Self-Driving but with a distinct technical approach. The system, described as ‘Level 2++,’ will incorporate additional safety guardrails and is expected to expand to more Toyota models by 2030.
Toyota’s New ADAS: What to Expect
Toyota’s upcoming ADAS will build on its current offerings, which include adaptive cruise control with lane centering, lane change assist, and auto park. The new system, set to debut in 2028, is described as ‘Level 2++’—a term used by automakers to indicate capabilities that go beyond standard Level 2 but do not reach full Level 3 autonomy.
According to Japan’s Nikkei, this system will allow supervised point-to-point driving on highways and in cities, similar to Tesla’s Full Self-Driving. However, drivers will still need to remain attentive and ready to intervene at any time.
Toyota’s Guardrail Approach to Safety
Unlike Tesla’s reliance on end-to-end AI, Toyota plans to implement a ‘guardrail’ system that monitors the AI’s behavior and blocks unexpected actions based on parameters set by humans. This layered approach is designed to enhance safety and maintain explainability in the system’s decisions.
Akihiro Sarada, head of Toyota’s Software Development Center, explained, “We’ll develop Level 4 technology from a technical standpoint, but offer it commercially as Level 2++. We’ll proceed in a way that ensures both safety and explainability based on the technology.” While the underlying technology may be capable of higher autonomy, drivers will remain responsible for vehicle operation.
Deployment Timeline and Industry Context
Toyota plans to introduce the new system on its 2028 models and expand it to more vehicles by 2030. It is not yet clear which markets will receive the technology first.
Japan has already legalized Level 4 autonomous systems and aims to have around 10,000 Level 4 taxis, buses, and other vehicles on its roads by 2030. Toyota is also reportedly in discussions with Waymo to enter the robotaxi sector, though details and a timeline have not been disclosed.
Competitor Comparison
Other automakers are also advancing their driver assistance technologies. Mercedes-Benz is developing MB.Drive Assist Pro, and Rivian offers a comparable system called Autonomy+. These developments reflect a broader industry trend toward more capable and safer autonomous driving features.
Why this matters
Toyota’s move signals a shift among Japanese automakers, who have been slower to adopt advanced autonomous driving technologies compared to their U.S. and Chinese counterparts. By focusing on safety and explainability, Toyota aims to address concerns about AI-driven vehicle behavior and driver responsibility.
The introduction of these systems could influence regulatory standards and consumer expectations for advanced driver assistance features worldwide.
What this means for buyers
Buyers considering Toyota vehicles can expect more advanced driver assistance features starting in 2028, with a focus on safety and supervised autonomy. Those interested in fully autonomous or robotaxi services may see additional options as Toyota explores partnerships and expands its technology.
Consumers should stay informed about which models and markets will receive the new system first, and compare offerings from other automakers as the technology landscape evolves.
